swap

Interface

SPROUT_CXX14_CONSTEXPR void swap(basic_string& s) SPROUT_NOEXCEPT_EXPR(SPROUT_NOEXCEPT_EXPR(std::swap(std::declval<T&>(), std::declval<T&>())));

Postcondition

*this contains the same sequence of characters that was in s, s contains the same sequence of characters that was in *this.

Throws

Nothing unless one of the element-wise swap calls throws an exception.

Examples

#include <sprout/string.hpp>
#include <sprout/assert.hpp>
using namespace sprout;

auto x = string<8>("homuhomu");
auto y = string<8>("madocchi");
int main() {
  swap(x, y);
  SPROUT_ASSERT_MSG(x == "madocchi" && y == "homuhomu", "each element are swapped.");
}

Complexity

linear.
